all: add support for EIP-2718, EIP-2930 transactions (#21502)

Browse Source 
This adds support for EIP-2718 typed transactions as well as EIP-2930
access list transactions (tx type 1). These EIPs are scheduled for the
Berlin fork.

There very few changes to existing APIs in core/types, and several new APIs
to deal with access list transactions. In particular, there are two new
constructor functions for transactions: types.NewTx and types.SignNewTx.
Since the canonical encoding of typed transactions is not RLP-compatible,
Transaction now has new methods for encoding and decoding: MarshalBinary
and UnmarshalBinary.

The existing EIP-155 signer does not support the new transaction types.
All code dealing with transaction signatures should be updated to use the
newer EIP-2930 signer. To make this easier for future updates, we have
added new constructor functions for types.Signer: types.LatestSigner and
types.LatestSignerForChainID. 

This change also adds support for the YoloV3 testnet.

## EIP-2930 testing
This test contains testcases for EIP-2930, which uses transactions with access lists.
### Prestate
The alloc portion contains one contract (`0x000000000000000000000000000000000000aaaa`), containing the
following code: `0x5854505854`: `PC ;SLOAD; POP; PC; SLOAD`.
Essentialy, this contract does `SLOAD(0)` and `SLOAD(3)`.
The alloc also contains some funds on `0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b`.
## Transactions
There are three transactions, each invokes the contract above.
1. ACL-transaction, which contains some non-used slots
2. Regular transaction
3. ACL-transaction, which contains the slots `1` and `3` in `0x000000000000000000000000000000000000aaaa`
## Execution
Running it yields:
```
dir=./testdata/8 && ./evm t8n --state.fork=Berlin --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json --trace && cat trace-* | grep SLOAD
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}

{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}

```
Simlarly, we can provide the input transactions via `stdin` instead of as file:
```
dir=./testdata/8 \
&& cat $dir/txs.json | jq "{txs: .}" \
| ./evm t8n --state.fork=Berlin \
--input.alloc=$dir/alloc.json \
--input.txs=stdin \
--input.env=$dir/env.json \
--trace \
&& cat trace-* | grep SLOAD
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x47c86","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":1,"op":84,"gas":"0x49cf6","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x494be","gasCost":"0x834","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":1,"op":84,"gas":"0x484be","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x0"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
{"pc":4,"op":84,"gas":"0x48456","gasCost":"0x64","memory":"0x","memSize":0,"stack":["0x3"],"returnStack":[],"returnData":"0x","depth":1,"refund":0,"opName":"SLOAD","error":""}
```
If we try to execute it on older rules:
```
dir=./testdata/8 && ./evm t8n --state.fork=Istanbul --input.alloc=$dir/alloc.json --input.txs=$dir/txs.json --input.env=$dir/env.json
INFO [01-21|23:21:51.265] rejected tx index=0 hash="d2818d…6ab3da" error="tx type not supported"
INFO [01-21|23:21:51.265] rejected tx index=1 hash="26ea00…81c01b" from=0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B error="nonce too high: address 0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B, tx: 1 state: 0"
INFO [01-21|23:21:51.265] rejected tx index=2 hash="698d01…369cee" error="tx type not supported"
```
Number `1` and `3` are not applicable, and therefore number `2` has wrong nonce.
